Flying time from IAD to SAN

The total flight duration from IAD to SAN is 4 hours, 57 minutes.

This is the average in-air flight time (wheels up to wheels down on the runway) based on actual flights taken over the past year. It covers the entire time on a typical commercial flight including take-off and landing.

If you're planning a trip, you should also factor in extra time for the plane to pull back from the gate and taxi to the runway, as well as reaching the destination gate after landing. If you include this extra time on the tarmac, the average total elapsed time from gate to gate flying from IAD to SAN is 5 hours, 18 minutes.

Finally, pilots might want to estimate the flight time using an average flight speed for a commercial airliner of 500 mph, which is equivalent to 805 km/h or 434 knots. If you don't add any extra time to increase or decrease speed for take-off and landing, then at constant speed your flight time would be 4 hours, 30 minutes.

Note that if you fly the other direction, the flight time from SAN to IAD would be 4 hours, 19 minutes due to the effect of winds and the jet stream.

If you're booking a flight, make sure you check the scheduled departure and arrival times. You should also factor in airport wait times and possible equipment or weather delays. If you're trying to figure out what time you'll arrive at the destination, you may want to see if there's a time difference between IAD and SAN.
